In-Vehicle Temperature Sensor
WARNING: This page is about a different car, the 2015 Land Rover LR2, 2014 Land Rover LR2, and 2013 Land Rover LR2. However, it is still accessible from the selected car via links, so may be relevant.
The in-vehicle temperature sensor comprises a NTC thermistor and a motor. The sensor is mounted behind a grill on the driver's side of the instrument panel, adjacent the steering column.
NOTE:
The in-vehicle temperature sensor is only fitted to vehicles with a dual zone, automatic climate control system.
The motor is provided an electrical feed from the ATC module and draws cabin air in through the grill and over the thermistor. The thermistor receives a 5 V reference feed from the ATC module. By monitoring the returned voltage, the ATC module can calculate air temperature within the cabin.
